IUI 16hrs post trigger?


Hi, I was wondering if anyone had an

<a href="https://glowing.com/glow-fertility-program">IUI</a> done about 16 hours after trigger? I went in today for a follicle scan and blood work and was told I have two mature follicles(one at 24, and the other at 20) and my dr said I was going to be ready to trigger tonight or tomorrow. He ended up having me trigger tonight around 830 and wants me back at the clinic at tomorrow 1230pm for <a href="https://glowing.com/glow-fertility-program">IUI</a>. I usually ovulate on my own but they put me on Letrozole and I believe it made me ovulate early(cycle day 12). It’s my first

<a href="https://glowing.com/glow-fertility-program">IUI</a> but from what I’ve read I know that 16hours after trigger is really early. I’m thinking it’s cause my follicles are really matured? Has anyone had experience with this or know if it’s possible for the egg to release earlier than 24hrs?
